Abstract
A tensioning device for tensioning a traction mechanism of a belt drive comprises a base member; a first tensioning arm pivotably supported on the base member and carrying a first tensioning roller; a second tensioning arm pivotably supported on the base member and carrying a second tensioning roller; a spring arrangement with first and second springs arranged to be effective between the first and second tensioning arms; wherein the two tensioning arms, when being pivoted relative to each other within a first tensioning angle range, are force-loaded against each other by the first spring, wherein the second spring is force-free relative at least to one of the tensioning arms; and wherein the tensioning arms, when being pivoted relative to each other within a second tensioning angle range comprising larger tensioning angles than the first tensioning angle range, are force-loaded against each other by the first spring and the second spring.
